Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, safety gloves.
Safety Warning: Disconnect the negative battery terminal to prevent accidental airbag deployment.

2. Check and Repair Wiring

Inspect Wiring: Use a multimeter to check for continuity in the airbag system wiring harness.
Repair or Replace Damaged Wiring: If any wires are frayed or broken, repair them using solder and heat-shrink tubing or replace the entire harness as necessary.

3. Replace Faulty Components

Airbag Module Replacement: If the airbag module shows fault codes indicating failure, remove the dashboard cover and disconnect the airbag module connectors. Replace with a new OEM module and reconnect.
Crash Sensor Replacement: If crash sensors are faulty, remove them from their mounting points and replace with new sensors. Ensure proper alignment during installation.

4. Reset Airbag System

Reconnect Battery: After all repairs, reconnect the negative battery terminal.
Clear DTCs: Use the OBD-II scanner to clear any existing airbag error codes and ensure the system is functioning correctly.

5. Final Inspection

Test Functionality: Perform a functional test of the airbag system to confirm that the airbag light is off and that all components are operational.
